Sixteenth-Brick D2Ds regulate 50W from Wide Input Range

Semiconductor Circuits, Inc. introduced an extension of its offering of ultra-wide input range 16th brick dc-dc converters. These open frame modules provide up to 50W of output power at output voltages of 1.8-, 3.3-, 5.0-, and 12-Vdc. They are designed for distributed power architecture applications or for use as a fully-regulated intermediate bus converter. These modules are compliant with DOSA 16th-brick footprint and interface standards. It has a wide input voltage range of 9 to 36 Vdc and provides 2250 Vdc input-to-output isolation.

The CPT 4:1 input series meets EN 60950 basic insulation requirements and is UL94 V-0 flammability rated. The module complies with all of the typical industry requirements including no load operation, 2X nominal input voltage transient and pre-biased load startup. Other features include: fixed-frequency operation, auto-restart OVP, OCP & OTP protections, UVLO, remote sense and +/-10% output voltage trim using industry standard equations. Remote ON/OFF is standard with positive or negative logic options available.

The modules feature a standard 16th-brick pinout with dimensions of 1.3" L x 0.9" W (33.02mm x 22.86mm.) It has a maximum height of 0.37″ (9.4mm) which accommodates tight card spacing with minimal airflow blockage of downstream components. Other output voltages in the 4:1 input series are available upon request.
